Abstract (en)
The present specification relates to a method for transmitting uplink data on the basis of a codebook in a wireless communication system, and an apparatus therefor. According to the present specification, disclosed is a method by which a terminal performs the steps of: receiving, from a base station, downlink control information (DCI) for determining a precoding matrix to be applied to the transmission of an uplink signal; determining, on the basis of the DCI, the precoding matrix to be applied to the transmission of the uplink signal from a codebook subset related to the transmission of the uplink signal; and transmitting the uplink signal to the base station on the basis of the determined precoding matrix, wherein the codebook subset includes at least one specific precoding matrix for full power transmission on the basis of the changing, in every antenna port pair, of the difference between phase values applied to antenna ports for the transmission of the uplink signal.
